Question 380
At the Dartwood regional data center, after onboarding a second AI project, a GPU kernel assigns neighboring threads radically different conditional paths and expected speedup disappears. Which maintenance practice best addresses the continuing risk?
Explanation
Correct Answer
This practice addresses future change, not just today’s incident. The team should inspect execution divergence after major algorithm changes because groups of GPU execution threads can lose efficiency when they follow divergent control paths. This directly addresses the reported issue at the Dartwood regional data center.
Incorrect Answers
This routine applies to gpu memory locality, but it does not maintain the specific correction needed for the problem at the Dartwood regional data center.
That practice helps control a different risk: mature software tooling and accessible model components help more teams adopt AI without implementing every kernel. The recurring control here should be to inspect execution divergence after major algorithm changes. For the Dartwood regional data center, the priority is to restructure suitable data-parallel work to reduce excessive branch divergence where practical.
This maintenance work is reasonable for data storage and network advances. The continuing exposure described here is that groups of GPU execution threads can lose efficiency when they follow divergent control paths. For the Dartwood regional data center, the priority is to restructure suitable data-parallel work to reduce excessive branch divergence where practical.
